Yes.
Being left to scream myself to sleep, standing in my cot desperate for someone to come, even if it meant they yelled at me or smacked me.
Left in the backs of cars to sleep, left home alone (with my younger sister) from the age of 6 upwards with next door listening through an intercom. Whilst it was a semi and they were the other side of a wall, it was also a 3storey victorian job, 5 beds and a cellar so much scope for a kid to be way out of range of the intercom.
Left in a rented home at just turned 16, mother was sectioned following a suicide attempt - her then boyfriend called an ambulance, she was packed into it.. and he fucked off home (which was 200 miles away) and left me there.
Six weeks. I lived on the £20 a week I got for minding a dog each day, and what was in the cupboards (I assume rent and bills were on direct debits) but the owners then went on holiday for a month and took the dog so that ended after week two..
A friends parent sussed something wasn't right but clearly didn't want to get that involved, she dropped off a bag of shopping once, which was kind of her.
I was still working at a local youth club, running the tuck bar so I started nicking a couple of quid out of the till and going to the chip shop so I could have a hot meal.
I did tell my Dad (also 200 miles away) but I dunno if he didn't grasp the severity of the situation or just couldn't handle it, or possibly I played it down as he didn't do anything for another four weeks, when he eventually came to get me.
I don't know why, to this day, I didn't actually tell someone, I had people I could have told - friends of family, youth club leaders, there definitely were options. I think I had already learned at that point that what would likely result is everyone being very concerned and upset... but no actual action. I was also terrified of the local kids home where another friend ended up at a similar age so that might be why.
